There are well documented studies on this Quote Geneticist and exercise physiologist Claude Bouchard at Laval University in Quebec City, has run numerous experiments comparing two populations, French-Canadian and West African students. Using long needles inserted into the thighs of test subjects, Bouchard's team extracted tiny sections of fibers, which look to the naked eye like pieces of raw meat. They were chemically treated to reveal metabolic differences, put on a glass slide, and slipped under a high-power microscope, where they appeared as a collage of tiny red and white crocodile scales. The West Africans, by a ratio of approximately two to one, had more of the larger fast-twitch fibers. The researchers concluded that the force generating capacity of type-II muscle fibers at high velocity, the speed and tempo of movements, and the capacity of an individual to adapt to exercise training are all genetically influenced. Although physical activity can improve fitness, it generally cannot alter a person's biological endowment by converting fast-twitch fibers to slow-twitch ones, or vice versa (although people do gradually and permanently lose fast-twitch muscles as a result of aging). It's estimated that 40 percent is due to environmental influences such as exercise, whereas 45 percent is associated with genetic factors (the remaining 15 percent is due to sampling error). At the far end of the performance bell curve in sprinting, where small differences can be crucial, genetics clearly circumscribes possibility. http://run-down.com/guests/je_black_athletes_p2.php Link to comment

So it is up to you to decide how much importance to give to them. Also one thing to note is that nearly all these studies are made by western people. Link to comment

Studies backed by what you seeing with your own eyes cannot be ignored Link to comment
